The historic Mine Ban Treaty (commonly called the Ottawa Treaty) was opened for signature at a treaty-signing conference held in Ottawa, Canada. The Canadian government had initiated the “Ottawa process” and hosted an international conference in Ottawa that led to the treaty; the Ottawa meeting set the stage for a December 1997 signing conference which the Government of Canada offered to host [1]. The treaty was officially open for signature in Ottawa on 3 December 1997, following adoption earlier in 1997, and is therefore associated with Ottawa—the capital city of Canada [3].
